FarSync Flex USB Sync/Async with Bit Error Rate Test (BERT) line quality tester + cables
The FarSync BERT provides a comprehensive, simple to use, all in one, line testing utility for testing asynchronous and synchronous lines from your Laptop PC. There are no extra expensive modules to buy to test different line types. All the popular standard BERT test patterns can be selected; the test period can be controlled; real time error counters and user controlled error injection with full line test statistics are provided. Lines with network interfaces RS232C (V.24), V.35, RS530 (EIA530, RS422), X.21 (V.11) and RS449 can be tested with line speeds ranging from 15 baud up to 2 Mbits/s.
The FarSync Flex adapter is simply plugged into any of your Laptop's USB ports; select one of the cables provided to connect to the line to be tested; the BERT application can then be started and the line quality results are displayed in real time.
